On that day, the fog blocked everything.

On that day, he became the captain of a ghost ship.

On that day, he stepped through the thick fog and confronted a completely subverted and fragmented world— the old order had vanished, strange phenomena dominated the endless seas beyond civilized society, and isolated island city-states and fleets of ships challenged the sea that had become the last ember of lights for the civilized world. All of this while the shadows of the old days were still stirring in the deep sea, waiting to devour this world that was about to die.

But for the new captain of the ghost ship Vanished, there was only one question he had to consider first — Who knows how to drive this ship?!

Heed my call! O’ Dragon of Eternal Sin, the Progressive Disaster, the Forerunner, the Land of Eternal Peace, the Flames of Soul Burning, He Who Owns The Deep Soul, the Sound of Origin, the First Cause of All Things, the Principle of Circles… o’ great Negary, your servant calls for your return!

Within the darkness, someone was harmoniously chanting, he was smiling, as he knew he would finally become one with his God.

And all of this, came from the remnant soul that was deceived to travelling to a different world and had his Protagonist Aura stolen.

Amid the steam of the industrial revolution, mysteries surge beneath the surface. Cults and secret societies seek the extraordinary in the shadows, while hidden gods gaze upon humanity from the heavens.

Forbidden knowledge, sacrificial rituals, and forgotten histories—mystery is everywhere.

Dorothy, unexpectedly transported to this increasingly bizarre world, discovers that to survive and move forward, she must adhere to one principle:

Knowledge is power.

And forbidden knowledge?

That’s an even greater power!

In her third year living in this steampunk world, Ciel gained the ability to simulate both the past and the future.

These simulations turned into a game where she could act without restraint, and after countless trials, real life became a replica she could navigate as though speedrunning it.

Churches, potions, mutations, the Old Gods, witches, sealed artifacts… none of these have anything to do with Ciel. She’s just an ordinary girl who wishes for a peaceful life.

She just happens to be particularly skilled at snuffing out danger before it even begins.
